Gravity G12BD1 12" Powered Subwoofer Enclosure

The Gravity G12BD1 is a loaded 12-inch car subwoofer enclosure designed to add dedicated low-frequency output to a vehicle audio system. It combines a pre-mounted Warzone Series subwoofer with a vented enclosure, providing a space-conscious way to add bass without building a custom box. Product listings describe an integrated amplifier for an all-in-one installation approach.

This enclosure is intended for drivers who want stronger bass response than factory full-range speakers can provide. Its ported enclosure design is tuned to reinforce low frequencies and give bass notes more presence. The 4-ohm final load also makes system matching more straightforward when planning the rest of the audio system.

The G12BD1 is rated for 500 watts RMS and 1,000 watts peak power. The enclosure provides 2.00 cubic feet of internal air space and is tuned to 38 Hz. These characteristics suit listeners seeking extended, low-frequency reinforcement from a single 12-inch enclosure.

Gravity uses a heavy-duty MDF enclosure construction for rigidity and durability. The loaded driver is pre-installed and wired to its final 4-ohm impedance, reducing the work involved compared with sourcing a separate subwoofer and enclosure. Its black finish is designed to integrate neatly in a trunk or cargo area.

Before purchase, measure the intended mounting location and plan for secure installation. The published enclosure dimensions are 20 x 17 x 17.5 inches, so it is best suited to vehicles with adequate trunk or cargo space. Verify the amplifier configuration, power wiring requirements, and included accessories with the selling dealer before installation.

• Pre-Loaded MDF Box: Reduces the need to build and wire a separate enclosure.

Design & Installation

The G12BD1 uses a black, heavy-duty MDF wedge-style enclosure with a vented design. Its 2.00-cubic-foot air space and 38 Hz tuning are part of the assembled enclosure package. The subwoofer is pre-loaded and pre-wired at a 4-ohm final impedance.

Install the enclosure in a dry, secure trunk or cargo-area location where it cannot move while driving. Confirm that the 20 x 17 x 17.5-inch enclosure will fit before ordering, and allow suitable clearance for any amplifier section and wiring connections. Product listings identify the unit as powered, but the published amplifier electrical details and wiring-kit contents should be verified with the dealer.
